Serial No. 360,391.

This invention relates to a feeder system for a mercury boiler thatcomprises a plurality of horizontally disposed headers installed side byside.

The invention wili be understood from the description in connection withthe accompanying drawing in which Fig. 1 is a vertical section partlybroken away through an illusirative embodiment of the invention takenalong the line 11 of Fig. 2; Fig. 2 is a section taken along the line 22of Fig. 1; and Fig. 3 is a plan View taken along the line 3-3 of Fig. 1.

In the drawing reference character 1 indicates a mercury feed pipethrough which liquid mercury enters from any convenient source. pipe orheader 2 that is provided with avalved drain 3 at the bottom thereof.The cross pipe or header 2 is provided with branches The pipe 1 isconnected to a cross.

4 that lead to aligned headers 5 that are 7 located at substantially thesame level as the headers of the mercury boiler itself. Liquid mercurytubes 6 lead from the lower sides of the headers 5 into the ends of themercury boiler headers 7 and equalizing tubes 8 lead from the vaporspace of the headers 7 to the upper sides of the headers 5.

V The row of horizontally disposed headers 7 of the mercury boiler islocated at the upper end of the furnace 9 and depending tubes 10 fromthe lower sides of the headers 7 extend into the furnace in the usualmanner.

The headers 7 are supported from above by means of rods 11 that areconnected to the upper sides of the headers and extend from fixedsupports 12.

By the arrangement of the feeding system above described, thedistribution is such that a uniform flow of liquid mercury is providedto all sections of the boiler and the level in all headers of the boileris equalized. The drain pipe 3 is provided so that the mercury 1 can bedrained out into a separate tank or vessel in case one of the tubes 10becomes ruptured.

Changes of temperature in the metal of tubes, headers'and connectedparts do not result in any stresses suificient to cause leaks
